HYBRIT and H2 Green Steel have launched projects in Sweden with a target to manufacture 10 million tonnes (mt) of fossil fuel-free crude (green) steel per year by 2030. Success, of course, depends on the numbers adding up, or rather, the numbers going down.

To make green steel, you need green hydrogen; to make green hydrogen, you need cheap renewable energy. HYBRIT and H2 Green Steel believe this will come from wind power at a LCOE of $30 per megawatt-hour. With the trajectory of costs for renewable energy going ever downward, it is likely they will be able to achieve this.

Add to the mix the increasing costs of carbon and the pressure to decarbonize, and you have a winner. It is expected that a carbon credits will be available to green steel producers of around $85 per ton.

About a decade ago, MIT researchers discovered a technique that speeds physics modeling by 1000X. They spun this out into a new company, called Akselos, which has been helping enterprises to weave the tech into various kinds of digital twins used to improve shipping, refining, and wind power generation.

A digital twin is a virtual representation of an object or system that spans its lifecycle, is updated from real-time data, and uses simulation, machine learning, and reasoning to help decision-making. Connected sensors on the physical asset collect data that can be mapped onto the virtual model.

The specific innovation improves the performance of finite element analysis (FEA) algorithms which underpin most types of physics simulations. Akselos experience over the last decade can help executives explore the implications of the million-fold improvements in physics simulation that Nvidia is now demonstrating thanks to improvement in hardware, scalability, and new algorithms.

iSun has won a massive solar canopy order. But who’s buying?

There are not many things I love more than a solar power canopy that charges an EV charging station. It’s all right there — transferring sunlight into electricity and then using that electricity to power a modern electric car; driving on sunshine.

So, it’s quite exciting to see that iSun (NASDAQ: ISUN) has been awarded a contract to provide 1,780 solar power canopies for EV charging stations. The problem is: we don’t have much more detail than that. We don’t know where these charging stations are and don’t know who is procuring the solar canopies.

RWE is using used lithium batteries from electric vehicles in the new storage unit. The 60 battery systems in the innovative storage unit on the site of the RWE pumped storage power plant in Herdecke, North Rhine-Westphalia, can buffer around 4.5 megawatt hours of electricity.

At the touch of a button, the car changes colors.

The surface coating of the BMW iX Flow featuring E Ink contains many millions of microcapsules, with a diameter equivalent to the thickness of a human hair. Each of these microcapsules contains negatively charged white pigments and positively charged black pigments. Depending on the chosen setting, stimulation by means of an electrical field causes either the white or the black pigments to collect at the surface of the microcapsule, giving the car body the desired shade.

Just don’t expect to see this at your local BMW dealership anytime soon: the automaker says this is just an “advanced research and design project.”

Even though solid state batteries are seen as technology that could drastically improve today’s fully-electric vehicles, it seems the first vehicles to feature one won’t actually be EVs. This is at least true in Toyota’s case since the manufacturer has now confirmed that its first solid state-equipped vehicles will be hybrids expected to debut in two or three years’ time.

The news comes from Gill Pratt, Toyota’s chief scientist and head of the Toyota Research Institute, who made the announcement during an interview for Autoline. He also mentioned that the manufacturer has made progress with its solid state project and that development is on schedule.

He did not say which hybrid Toyota will get a solid state battery, but he did go on to explain why it won’t immediately offer solid state EVs. The main reason has to do with the size of the battery pack, which for a hybrid vehicle that still has an internal combustion engine, is considerably smaller than what you see in pure EVs.

On January 6, 2022, a Tesla Model S P85 (the oldest performance version) reached an impressive mileage milestone of 1,500,000 km (932,256 miles).

The car is used in Germany by Hansjörg von Gemmingen — Hornberg, who is known in the EV world for setting the highest mileage records in Tesla cars.

A wind turbine sitting idle on a calm day or spinning swiftly when power demand is already met poses a problem for renewables, and is one researchers think can be tackled under the sea.

In one vision, offshore wind farms could use seawater to essentially store energy until it’s needed, helping wean humanity off fossil fuels.

“We came up with a solution that we call the ocean battery,” Frits Bliek, CEO of Dutch startup Ocean Grazer told AFP while showing off the system at the CES tech fair in Las Vegas.

All-solid-state batteries are now one step closer to becoming the powerhouse of next-generation electronics, as researchers from Tokyo Tech, National Institute of Advanced Industrial Science and Technology (AIST), and Yamagata University introduce a strategy to restore their low electrical resistance. They also explore the underlying reduction mechanism, paving the way for a more fundamental understanding of the workings of all-solid-state lithium batteries.

All-solid-state lithium batteries have become the new craze in materials science and engineering as conventional lithium-ion batteries can no longer meet the standards for advanced technologies, such as electric vehicles, which demand high energy densities, fast charging, and long cycle lives. All-solid-state batteries, which use a solid electrolyte instead of a liquid electrolyte found in traditional batteries, not only meet these standards but are comparatively safer and more convenient as they have the possibility to charge in a short time.

However, the solid electrolyte comes with its own challenge. It turns out that the interface between the positive electrode and solid electrolyte shows a large electrical resistance whose origin is not well understood. Furthermore, the resistance increases when the electrode surface is exposed to air, degrading the battery capacity and performance. While several attempts have been made to lower the resistance, none have managed to bring it down to 10 Ω cm² (ohm centimeter-squared), the reported interface resistance value when not exposed to air.
